Hi everyone - my ICF-C1 clock radio runs fast, gaining about 1 minute and 20 seconds every month. I cannot locate a schematic for this clock radio, so I am unsure if I can modify an RC/crystal circuit to adjust the timing or whether this uses the 60hz mains frequency as a reference. Has anyone had any luck in locating a schematic diagram or in replacing a resistor or capacitor to have more accurate time? Technician with 30 years experience here, just looking for a diagram or helpful advice.
Thanks,
Rick
